Product Application of Dibutyl sebacate (CAS# 109-43-3)
Dibutyl sebacate (DBS), a dibutyl ester of sebacic acid, serves as a versatile component in multiple industries. It is widely employed in plastics for food packaging and medical devices, as well as in pharmaceutical applications. Additionally, DBS acts as a desensitizer in Otto fuel II, a monopropellant used in torpedo systems. The compound also functions as a plasticizer in the preparation of free ethylcellulose films. Furthermore, it can be utilized as a core material in liquid-core capsules, where the capsules feature a cross-linked alginate/polyacrylamide membrane created through the co-extrusion jet-break-up method, specifically designed for the extraction of the pesticide atrazine.
